[A water reservoir is a human-made lake that is created when a river is dammed to serve one or more purposes, such as to generate hydropower production, provide a water supply for drinking, irrigation, and flood protection] (www.eea.europa.eu). The effects of water reservoirs on the environment have stirred controversy since their introduction. Though water reservoirs can create many sought out improvements for a society it can detrimentally impact natural habitats and spawn a number of environmental complications. The debate on whether water reservoirs are truly beneficial or harmful towards human populations is ongoing as new projects like the Three Gorges in China are concluded. In the following essay I will be giving a critical review on the various negatives that arise from the creation of a water reservoir. The creation of a water reservoir will have a significant impact on the natural habitats that existed prior to its building. The surroundings around the damn will be inundated and reclaimed as part of the newly created water reservoir. The runoff of the initial filling of the reservoir will cause the existing plant life to die and decompose. For the first years stabilization will take place where the rotting plant life releases an abundance of carbon back into the atmosphere. Further on, the decomposing of plant material that settles at the bottom of the reservoir will produce and release large amounts of methane. A weakness to the argument that a water reservoir is green-friendly. Not only does local plant life and animal life suffer from this loss of land, the river itself is affected through vaporization. A water reservoir creates a greater surface area by which more water is evaporated and depleted from the ... ... middle of paper ... ...an produce a pollution factor comparable to that of an oil driven power plant.

    The negative aspects of Glen Canyon Dam greatly exceed the positive aspects. The dam’s hydroelectric power supply is only three percent of the total power used by the six states that are served by the facility. There is a surplus of power on the Colorado Plateau and with more and more power-plants being created in the western hemisphere, Glen Canyon Dam’s power is not needed (Living Rivers: What about the hydroelectric loss). Although the ‘lake’ contains twenty seven million acre feet of water, one and a half million acre feet of water are lost yearly due to evaporation and seepage into the sandstone banks surrounding the ‘lake’ (Living Rivers: What about the water supply?). The loss of that much “water represents millions, even billions of dollars” (Farmer 183). If the government were to employ more water efficient irrigation practices, as much as five million acre feet of water per year could be saved.

    In the World, the liquid medium that we know as water is the main component that keeps humans, animals and their respective ecosystems alive. Everything from trees down to the smallest leaf requires it, and it is required for any lifeform to continue to grow. Though as humanity expands and continues on an upward slope, humans as a lifeforce continue to need more. Water is a defining aspect of a community, and with the ever-rising population and human-crafted climate change coming to an all-time high, one of the most important water origins of the southeast region is coming to a very dangerous low.

  • Why Diverting Water From the Great Lakes Region is a Bad Idea

    687 Words  | 2 Pages

    Water is the foundational basis of life on Earth. Ecosystems, society and humans are completely dependent on it, and as the world population continues to grow, there will be more mouths to feed, and those people will need water to continue their daily lives. However, shortages and poor management leads to the destruction of natural habitats and human suffering. Desertification of land in China is ever-increasing, turning green, lush land into desert. However, this is due mainly in part, because of human activity, and global warming (Wang, Yang, Dong, & Zhang, 2009). The United States could experience a crisis similarly to China’s, but for now they have averted such a catastrophe, because of heavy regulation of water. Though there are water shortages in many parts of the world, it is unwise to export water from the Great Lakes to those regions. Two major reasons why diverting the Great Lakes is a terrible idea, one: it allows for waters wars to start on the basis of who is allowed to access it and for commodification purposes. Two, diverting water on such large scales could have cataclysmic effects on the local residents as well as the environment.

    In the area of the Great Lakes, eastern Georgian Bay houses thousands of miles of marshlands and wetlands. These areas are some of the most threatened habitats in the world because they form where human development is highly concentrated, near the coast. Yet, the uninhabited wetlands are sometimes taken over by beaver dams. The water chemistry of these marshes depends on their location and connection with other bodies of water. Scientists Amanda Fracz and Patricia Chow-Fraser hypothesized that open wetlands

  • Essay On The Three Gorges Dam

    1157 Words  | 3 Pages

    In the beginning of the construction of the Three Gorges Dam, there were several problems. There were several protestors and opinions about the dam before the Three Gorges Dam project was even started.1 China has had history of several dam failures in the mid-1970s that were responsible for thousands of deaths. The three gorges (Xiling, Wu, and Qutang) have scenery that is a tourist attraction.2 The dam was going to be a little over 600 feet tall, 7500 feet wide, and hold over 97 trillion gallons of water. Because of all of the population increase, China started using coal power plants1 and shipping, which causes acid rain over the region making the Yangtze River is one of the most polluted rivers in the world.4 It does not help that the Yangtze River runs right through Chinas industrial heartland. Using the river to transport their goods to other parts or China adds to the pollution.2 Pollution from mines, hospitals, and garbage dumping is another big problem for the river because the pollution is building up around the dam.1 With the Three Gorges Dam will come landslides because of the rising water tables and the large slopes with unstable soil from local farming causing more sediment being added to the river.3 And because the dam lies on a fault line there will also be an escalation of earthquakes. There is a huge decrease in sediment discharge; which caused a 90% sediment load into thousands of other reservoirs. Before the dam was operational, it was retaining water and sediments.4 The water levels were rising faster than anyone expected, therefore, the finish date had to be moved up.1 Scientists even projected that 70% of sediment discharge would be trapped for the first two decades and 44% would be store...

  • The Damnation Of A Canyon by Edward Abbey

    923 Words  | 2 Pages

    Edward Abbey's heart lies in the once beautiful Glen Canyon. He describes all of his wonderful childhood stories of him floating down the river and how all it took was a paddleboat and little money. He tells of the great beauty of all the animals, insects, forestry, and ancient scenery the canyon once had. This is why Abbey feels reservoirs are doing terrible things for not only Glen Canyon but every river. When you think about it, a natural river untainted by the ways of machinery and humans is virtually non existent today. Any river large enough to have a dam and produce a substantial amount of electricity probably already has many of them doing so. Abbey feels they are ruining the environment and wildlife is being sacrificed. The risen waters of the reservoir drown all of the life that once lived. All of the beautiful scenery and historic sights are replaced by water marked rocks, muddy banks, and very small amounts of forestry and greenery. He believes the whole river is completely disrupted with every reservoir and dam. He highlights the fact that exploring the river now requires a tour guide boat or enough money to buy your own. Overall, Abbey does give some good reasons behind his opinion. However, I have a different belief on the matter. Although Edward Abbey uses strong personal experiences to persuade the reader to argue that the man made reservoirs are destroying the beautiful canyon and the environment, I think he overlooks the other possible opinions and the benefits of having them.

    Yet, there is no such thing as “clean hydro power,” with the exception of very small-scale hydropower dams at the individual or neighborhood level. Hydro powered dams can cause major fluctuations in downstream flows, and even dewater the stream channel, leading to direct death of fish and other species. The main effects of a dam on a river is that it disrupts flows, lowers water quality, blocks the movement of rivers vital nutrients and sediment, destroys fish and wildlife habitat, and eliminates recreational opportunities. Reservoirs slow and broaden rivers, making them warmer, reducing water quality, and harboring destructive nonnative species that scatter throughout the watershed and prey on and compete with native wildlife. The environmental, economic, and social impacts of a dam and reservoir may run the entire length of the river from the highest mountain peaks that feed the headwaters to the river’s outlet at the ocean according to

  • Tragedy Of Commons: Dam As A Tragedy Of The Commons

    A large issue we have that effects multiple different areas of our communities, are tragedy of the commons, which are actions that are rational but lead to irrational outcome. Government needs to take responsilbities to enforce rules for commons so they can diminish tragedy of the commons. Dams are a tragedy of the commons that only recently were come to the realisation of its more negatives effect they have on our world. Dams used to be seen as only positive, for their productful factors such as hydroelectricity and water supply. In this essay, I will argue that dams are an example of a tragedy of the commons proven by the documentary, Damnation, by the directors Travis Rummel and Ben Knight by describing that dams are highly subtractable

  • The Colorado River

    1680 Words  | 4 Pages

    One of the largest geographic physical structures in the United States is the Colorado River. Human activity and its interaction with this great river have an interesting history. The resources provided by the river have been used by humans, and caused conflict for human populations as well. One of these conflicts is water distribution, and the effects drought conditions have played in this distribution throughout the southwestern region. Major cities such as Las Vegas, Los Angeles, San Diego, and other communities in the southwest depend on the river. It provides water for over 20 million people, irrigation for 2 million acres of land, four thousand megawatts of hydroelectric energy, and over twenty million annual visitors for recreation purposes. Also, once in Mexico, the river provides water to irrigate half a million acres of farmland, and municipal and industrial water for 2 million people living in this delta region. The river distributes its flow from lakes and canals along its journey as well. Due to climate change, human demand, natural forces like evaporation and human-induced climate change this water supply is in conflict. Also, a recent change that began in March of 2014 will bring a temporary water surge to the delta of the Colorado River for the first time in many years to help restore this region, and it’s possible it could reach the Sea of Cortez once again.

    The water is then used when there is a lack of supply. For example many small dams impound water in the spring, for use in the summer dry months. Storage dams also supply a water supply, or an improved habitat for fish and wildlife; they may store water for hydroelectricity as well.2 A diversion dam is a generation of a commonly constructed dam which is built to provide sufficient water pressure for pushing water into ditches, canals or other systems. These dams, which are normally shorter than storage dams are used for irrigation developments and for diversion the of water from a stream to a reservoir.
